The **TPC-315-RJ22A** is an industrial-grade Touch Panel PC designed for automation and human-machine interface (HMI) applications. Below is a breakdown of its core electronic components and technical specifications. --- ### 1. Core Processing & System Architecture The heart of this device is built on low-power, high-efficiency architecture suitable for 24/7 industrial operation. | Component | Specification | | :--- | :--- | | **Processor (CPU)** | Intel Celeron J1900 Quad-Core (2.0 GHz) | | **Memory (RAM)** | 4GB DDR3L SO-DIMM (Expandable) | | **Storage** | 64GB / 128GB mSATA SSD | | **Operating System** | Support for Windows 7/8/10 and Linux | ### 2. Display and Touch Interface The display assembly is integrated with an industrial-grade controller to handle environmental interference. * **LCD Panel:** 15-inch TFT LED display with a resolution of 1024 x 768 (XGA). * **Touch Controller:** Multi-point Projected Capacitive (P-CAP) touch screen. * **Durability:** Usually features an IP65-rated front bezel for water and dust protection. ### 3. I/O Connectivity (Electronic Interfaces) The "RJ" in the model name often refers to specific networking configurations or ruggedized RJ45 port layouts. | Interface Type | Quantity | Purpose | | :--- | :--- | :--- | | **Ethernet** | 2x RJ45 (Gigabit) | For LAN and Industrial IoT connectivity. | | **USB Ports** | 3x USB 2.0, 1x USB 3.0 | Peripherals and data transfer. | | **Serial Ports** | 2x RS232/422/485 | Legacy PLC and sensor communication. | | **Video Out** | 1x HDMI / VGA | Secondary display output. | ### 4. Power Supply Characteristics The internal power circuitry is designed to handle the fluctuations common in factory environments. * **Input Voltage:** 12V - 24V DC Wide Voltage Input. * **Protection:** Over-current, Over-voltage, and Reverse polarity protection. * **Power Consumption:** Typically low (approx. 20W - 30W depending on load). ### 5. Mechanical & Thermal Design * **Fanless Cooling:** The chassis acts as a large heat sink, removing the need for internal fans (reducing failure points and dust intake). * **Expansion Slots:** Often includes Mini-PCIe slots for Wi-Fi, Bluetooth, or 4G LTE modules. ---
